I went even further, removing ALL the power supply goodies, hooking up one 
of those 4 pin trailer wiring kits to feed it with an old old XT power 
supply.  MPI too.  With lots left over for hard drives.  With a HD63C09EP 
and a Disto 2 meg kit in it, with cmos simms, I can cover it with a 
furniture blanket with a darkroom thermometer laying above the memory, boot 
it up and see a 3 degree above room temp rise on the thermometer the next 
day.  The coco doesn't seem to make much heat, but its power supply 
efficiency is maybe 20%.
